should. 1 cylinder dead won't affect it enough to cause a no start. i wouldn't start it due to possibility of dropping a valve and destroying the engine. i replaced an engine in an impala that did just that and caused alot of carnage.

yes it will run. does it miss at all? easy to tell with cover off. or if you wanna be a nig run a compresson test and the cyl should be noticably different due to the spring being broke the valve wont fully seat.
